At culturachip.org you'll find various chiptune compos, a challenge for tune writers. Recently third microcompo for the AY chip with the collaboration of AAMSX has ended. The results are in. You can listen and download the songs visiting the culturachip website. Enjoy.

BTW, how do you play low-fi samples during music?
Have you included the samples in some audio format supported by open replayers?

It could be very cool to have this feature in some trackers and players (WYZtracker/player for example)
I bet also that by shifting the frequencies of the 3 channels of a sample one could make a sort of musical instrument to play simple musics.
Nothing that a pc tracker cannot handle

That is why I always bet for INDEPENDENT HARDWARE SOUND PROCESSING (Y8950,MOONSOUND,DEVELO BOX) because that give you more CPU resources for other things.
DEVELO BOX is my favorite at this moment I see a lot potential benefits.

Then, for example, only rotating bits the pitch of the sample will change in +-1 octave as a single freq? or I'm wrong?
If so, This is very interesting! the first thing to do is to sort the the channel's frecuency : A=high B= med C=low for a best manage of the calculations.
